Hi Julie,
Thanks for your quick response on this, I have tried the approach, Still no luck.
Now the variable is a global variable and I have checked it has a value of X. It is directly under context and available in the data view.
if(($record.gv_subj.isNull)
{
this.presence = "visible";
}
else
{
this.presence = "hidden";
}
Best Regards,
Tapo.
